REFRIGERATOR.

SPECIFICATION forming art of Letters Patent No. 522,118, dated June 26,1894.

. Application filed March 12, 1894.

T0 at whom it may concern:

Be it known that I, FREDERIK JACOBY, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inRefrigerators, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to a new and improved refrigerator and has forits object to provide a system of circulation of air and of ventilation,which will keep the provisionchamber fresh and clean, and at the sametime to so locate the ventilating openings and partitions that thecontact of the rising air with the ice in the ice-cham ber will beeifectually prevented.

A further object of the invention is to provide a system ofdrainage-troughs and adjustable hoods therefor, for a purpose which willhereinafter more fully appear.

In-the drawingsz-Figure l is a longitudinal vertical sectional view ofthe refrigerator taken on line 1--1 of Fig. 2. Fig. 2 is a transversevertical sectional view on line 2--2 of Fig. 1. Fig. 3 is a detailhorizontal sectional view takenon line 3-3 of Fig. 2. Fig. 4 is a detailhorizontal sectional view showing one corner of the ice-chamber.

Referring to the various parts by numerals, 1 designates the outercasing of the refrigerator; 2 the retail or supplementalprovisionchamber supported therein, said chamber being provided with anouter sliding door 3 which is connected by a chain or cord with an innerhinged-cover 4 in such a manner that when the sliding door is opened thehinged cover is closed and vice versa; 5 the icer chamber which issupported near the top of the refrigerator and is formed on all itsvertical sides with double, hollow walls 6. The ice-chamber is set up inthe corner of the easing of the refrigerator so that the walls of thelatterwill form the outer part of three or more of the double-walls ofthe ice-chamber, as shown. When the outer casing of the re frigerator isthus used to form the outer side of the double walls of the ice-chamberthe top and bottom of the hollow walls so formed are preferably leftentirely open, as shown at 7, to permit the free circulation of airtherein,

Serial No. 503 336. (No model.)

but with the wall of the ice-chamber which is formed independently ofthe outer casing suitable openings are preferably formed in the top andbottom'thereof to permit the circulation of air and the exit of thedrippings as shown at 8.

Located directlybelowand close to the lower open end of the ice-chamberis a stationary slatted ice-rack 9, and suitably supported at a properdistance below this rack is a series of parallel, slightly-inclined,stationary drainage-troughs 10. These troughs are located a suitabledistance apart and are provided at their lower ends with dependingdrainagetubes 11, and said tubes are connected at their lower ends by apipe 12, which pipe carries the drainage outside of the refrigerator.

Above the troughs 10 and extending over the space between them aresupported shaped hoods or deflectors 13 whose lower edges extend overthe adjacent sides of said troughs. These deflectors or hoods are formedat their ends with upwardly and outwardly inclined portions 14, theouter ends of said inclined portions extending out beyond theinner wallsof the ice-chamber in order to catch the drippings from said sides anddeflect them inwardly into the-troughs 10 and also prevent them fromsplashingonto the adjoining side-walls of the refrigerator and passingthence down into the provision chamber.

The hoods or deflectors 13 are supported on the upper ends of arms 15 ofhorizontal bars 16 located beneath the troughs l0 and at each end of thehoods. tween the troughs 10 and are slotted vertically as shown and thebars 16 are loosely secured to the sides of the refrigerator, so as tobe vertically movable, by means of headed bolts 17, which pass throughthe vertical slots inthe arms 15 and into the refrigerator side. The bar16 on its under side is inclined from its outer ends inwardly anddownwardly for a portion of its length, and these inclined portions arelongitu'dinallygrooved on their under sides.

The arms 15 pass up be-.

A stationary horizontal bar 18 is secured to the side of refrigeratordirectlybelow each 'bar 16 and in close proximity thereto and said barsare longitudinally grooved on their upper edges to receive tongues onthe lower straight edges of wedges 19, the upper edges of said wedgesbeing also formed with a tongue which engages the groove in the inclinedportions of the bar 16, as clearly shown in Fig. 2. Two of these wedgesare used for each bar 16, one at each end thereof, as shown.

The ceiling of the refrigerator is formed double, with an air spacebetween its two walls, and the inner wall thereof is formed with acentral longitudinal slot 20 which extends along the whole space betweensaid walls. The outer wall of the ceiling is provided with a series ofsmall openings near its longitudinal edges at opposite sides of saidcentral slot for the escape of the warm air. The entire space betweenthe walls of the ceiling is in communication by means of openings formedin the transverse spacing strips 21, which support the inner wall of theceiling.

The operation will be 'readily understood by reference to Fig. 1 of thedrawings, wherein the descending currents of cold air are indicated byarrows shown in full lines while the ascending currents of warmer airare indicated by arrows in dotted lines. The hoods 13 are raised fromthe troughs 10 a sufficient distance to permit the cold air to passbetween them in descending from the ice-chamber to theprovision-chamber, and the distance said hoods will be raised willdepend on the amount of ice in the ice-chamber. The object of thisadjustment is to prevent air rising through the ice-chamber byregulating the spaces between the troughs and hoods so that the spaceswill be just sufiieient to permit the passage of so much air as the icewill make cold. The warmer air will rise outside of the icechamber and aportion will pass through the central slot in the inner Wall of theceiling, and thence out through the openings in the outer wall thereof,By thus causing the air to flow tothe center of the top of therefrigerator and to take a circuitous path before escaping, a more evendegree of cold is produced over the whole of the refrigerator, and thecirculation of the air through the whole of the refrigerator is secured.

The object of forming the walls of the icechamber hollowand open at thetop and bot- 1 tom is to permit warm air to pass upwardly through them.

By locating the icechamber in one of the upper corners of therefrigerator and thereby bringing three of the hollow walls of theicechamber immediately adjacent to the refrigerator walls, it will beseen that a more complete circulation is caused through the hollow wallsthan would be the case if said hollowwalls were set out into therefrigerator.

The essential advantages of my construction are that the refrigeratorwill be kept very dry and will consume less ice than theordinarily-constructed refrigerator.

Having thus fully described my invention, what I claim is 1. Arefrigerator consisting of an outer casing, a provision-chamber, anice-chamber having vertical walls, an ice rack in said chamher, a seriesof troughs below said icechamher, and a series of hoods supported aboveand between the troughs and spanning the spaces between the same, theends of the hoods being inclined upwardly and outwardly, as shown, totake the drippings from the walls of the ice-chamber and direct theminto the troughs, substantially as described.

2. In a refrigerator, the combination of an outer casing, a provisionchamber and an icechamber, a series of separated drainagetroughssupported below the ice chamber, bars 16 adj ustably supported below thedrainage-troughs, said bars being beveled and grooved on their undersides, as shown, and provided with upwardly-extending arms, said armsextending up between the troughs, a series of hoods carried by"saidupwardlvextending arms and supported above the troughs, wedgessupported below and in engagement with the bars 16, said wedges beingformed with tongues on their upper and lower edges,

a grooved horizontal support for said wedges, the inclined portion ofthe wedges engaging the beveled portion of the bars 16 and their loweredges engaging the grooved horizontal support, substantially as and forthe purpose set forth. a

In testimony whereof I affix my signature in presence of two witnesses.

FREDERIK J ACOBY.
